Title: Frustrating the unauthorized copying of recorded data
Inventor: BROTBY WILLIAM KRAG
IPC: G06F21/12
Filed: 1983-11-01
Abstract: The authorized recorded disc 16 has a dedicated security track 14 associated with incrementing apparatus 12 in the jacket of the disc and which on a first revolution reads out a stored number N0 and increments it to N1 and in a second revolution writes N1 over N0 on track 14. When reading into computer 18 from disc 16 an initializing routine terminates with a security check in which a stored number N0 is incremented to N1 and compared with N1 on track 14. If the numbers are unequal because an unauthorized disc lacks the apparatus 12 or the latter has been tampered with, the security procedure destroys the main programme record. In another embodiment authorized discs are identified by a localized permanent defective area whose presence in the appropriate location is checked by determining whether it is possible to write on the area and read back what has been written. A blank disc which allows this triggers the obliteration of the record. A further embodiment uses tracks having a harder magnetic medium which constitute a read-only memory which cannot be erased by a copying device. <IMAGE>

Title: Control for automatic adjustment of the cowl of a shearer loader used in underground mining
Inventor: HENRICH FRIEDHELM
IPC: E21C25/14
Filed: 1986-05-01
Abstract: A control is used for automatic adjustment of the cowls 11, 12 of a shearer-loader machine 1 used in underground mining, each of the shearer drums 5, 6 being mounted on a pivotal carrying arm 9, 10. Each cowl 11, 12 can pivot about the drum axis 15 and each drum 5, 6 has an adjusting mechanism for the respective cowl. Angle detectors 31 detect pivotal movements of the drum-carrying arms 9, 10 and produce signals corresponding to the magnitude of the angles of the drum-carrying arms. Each detector 31 produces a signal which is proportional to the magnitude of the drum-carrying arm pivot angle beta  relative to a reference plane X and which is operative as a set-value signal for controlling the cowl-adjusting mechanism. Also, each cowl arm 13, 14 has an angle detector which detects the cowl arm pivot angle  alpha  relative to the longitudinal axis Y of the drum-carrying arm, and forms an actual-value signal. When the adjusting mechanism is actuated the latter actual-value signal adapts itself to the set-value signal and guides the cowl arms 13, 14 into positions parallel to the reference plane X and in which the cowl arm pivot angle  alpha  coincides with the drum-carrying arm pivot angle beta . <IMAGE>
